Caregiver training: Evidence of its effectiveness for cognitive and functional improvement in older adults.

AIMS AND OBJECTIVES: The objectives of this study were to assess the benefits of a caregiver training programme on the cognitive and functional status of older adults, and to compare the effects of this programme according to type of caregiver (professional vs. family caregiver). BACKGROUND: Due to demographic changes that have resulted in an aging population, the role of caregiver of an older adult has become very important in recent years. DESIGN AND METHODS: The sample was composed of 160 older adults: (a) 100 received care from caregivers who had taken the three-month training programme (treatment group), of which 60 were professional caregivers and 40 were family caregivers, and (b) 60 received care from caregivers who had not taken the programme (control group). In order to evaluate programme effects on cognitive and functional status, we used both direct measures answered by the older adults (MMSE, CAPE and EuroQol) and caregiver reports (Barthel and RMPBC). We used a quasi-experimental, pre-post design. We followed SQUIRE 2.0 guidelines for reporting. RESULTS: The results showed that older adults who were cared for by caregivers that had participated in the training programme showed gains in quality of life and cognitive ability and maintenance of functional ability. Within the treatment group, although everyone significantly improved their scores, the older adults cared for by family caregivers improved in more of the cognitive sub-items than did their peers in the professional caregiver group. CONCLUSIONS: The data obtained show that a caregiver training programme based on cognitive stimulation produces cognitive, functional and health-related quality-of-life benefits in older adults. Furthermore, the caregivers reported increased satisfaction with their work. RELEVANCE TO CLINICAL PRACTICE: The improvements obtained in the older adults and in caregivers show the relevance of this type of intervention when working in the clinical field of caregiving.

Effectiveness of Cognitive Interventions in Older Adults: A Review.

(1) Introduction: With older adults, cognitive intervention programs are most often used for preventing or reversing a decline in cognitive functions, but it has been recently noted that there are insufficient high-quality research studies that report the effects of cognitive intervention on the cognitive functioning of older adults. (2) Objective: To analyze the available evidence concerning the effect of cognitive interventions for improving or maintaining the general cognitive status of older adults who present different cognitive levels. (3) Method: a review of studies published between 2010 and 2019 using the following databases: PubMed, PsycINFO, Cochrane, Google Scholar, ProQuest and Medline. (4) Results: We selected 13 systematic reviews and/or meta-analyses. The results showed that the cognitive intervention programs improved general cognitive functioning and specific cognitive functions regardless of the initial cognitive level; that cognitive decline was slowed in older persons with dementia; and there was improvement in activities of daily living. Regarding duration of the results, benefits were maintained for periods of 2 months to 5 years. (5) Conclusion: Cognitive interventions have proven effective for maintaining and/or improving cognitive functioning in older adults regardless of their initial cognitive status. Even so, there are few studies that follow up these results to see whether they are maintained in the long term and whether there is transfer to other skills of daily life. However, we were able to observe in the present review how the participants' cognitive level varied according to sociodemographic differences, and to identify which components of cognitive programs make them more effective. Based on the results found, we highlight the importance of designing cognitive intervention programs that meet these effectiveness criteria, in order to maximize the positive effects of such programs when working with a population of older adults.

La fluidez verbal en personas mayores y su relación con variables psicosociales y de funcionamiento cognitivo / Verbal fluency in older people and its relationship with psychosocial variables and cognitive performance

Introducción: El análisis de la fluidez verbal en la vejez ha sido una de las principales estrategias como parte del diagnóstico de la demencia. Así, los estudios han demostrado que, en comparación con ancianos sanos, las personas con demencia muestran un deterioro significativo en fluidez verbal -especialmente en fluidez semántica- incluso después de controlar estadísticamente variables como la edad y el nivel educativo. Objetivo: El objetivo del estudio realizado es analizar la ejecución de personas mayores en una tarea de fluidez semántica y relacionarla con su rendimiento en otras tareas cognitivas (memoria de trabajo, atención y una prueba de screening), así como determinar la influencia de variables como el nivel educativo, la edad y el sexo en el rendimiento en la tarea de fluidez. Método: En el estudio han participado un total de 264 personas con una edad media de 79.57 años de la provincia de Granada. Los participantes han sido evaluados con una entrevista estructurada de variables psicosociales, una batería de evaluación neuropsicológica que incluye pruebas de fluidez, memoria, atención, y funcionamiento cognitivo general. Resultados: Los resultados muestran diferencias significativas en fluidez verbal en función del estatus cognitivo de las personas y del rango de edad. Igualmente se observan correlaciones significativas entre la fluidez y el resto de pruebas cognitivas aplicadas, siendo una prueba de screening cognitivo la que mejor predice la ejecución en fluidez. Conclusiones: Los datos obtenidos corroboran la importancia de la utilización de pruebas de fluidez en la evaluación psicológica de las personas mayores

Introduction: The analysis of verbal fluency in old age has been one of the main strategies as part of the diagnosis of dementia. Thus, studies have shown that, compared to healthy elderly people, those with dementia show a significant deterioration in verbal fluency -especially in semantic fluency- even after the statistical control of variables such as age and educational level. Objective: The objective of the study is to analyze the performance of older people in a task of semantic fluency and relate it to their performance in other cognitive tasks (working memory, attention task and a screening test) as well as to determine the influence of variables such as educational level, age and gender in the fluency task performance. Method: A total of 264 people with an average age of 79.57 years from the province of Granada participated in the study. Participants were evaluated with a structured interview of psychosocial variables, a battery of neuropsychological assessment that included tests of fluency, memory, attention, and general cognitive functioning. Results: The results showed significant differences in verbal fluency based on the cognitive status of the persons and the age range. Likewise, significant correlations were observed between fluency and the rest of past cognitive tests, the cognitive screening test being the best predictor of fluency performance. Conclusions: The data obtained corroborate the importance of the use of fluency tests in the psychological assessment of the elderly
